Which of the following terms describes the growth phase of hair?

The term that describes the growth phase of hair is "Anagen." This phase is significant because it is when the hair follicles are actively producing new hair. During the Anagen phase, hair may grow continuously for several years, with the length of this phase varying from person to person, and from one type of hair to another. This is crucial for understanding hair growth cycles in general, as it signifies the period where maximum hair production occurs.

In contrast to the Anagen phase, the other terms represent different stages of hair growth. The Catagen phase is a transitional stage where hair growth slows and the hair follicle shrinks. The Telogen phase is the resting phase, where the hair is not growing and is eventually shed. The Exogen phase refers to the part of the process where old hair is expelled from the follicle, ending the lifecycle before new hair begins to grow again. Understanding these differences helps in comprehending the complete lifecycle of hair and the factors that influence hair health and growth.
